CEMENT-BRICK MOLD.

SPECIFICATION formingpart of Letters Patent No. 740,024, dated September 29, 1903. Application filed J'une 8,1903. Serial No. 160,506. (No model.)

' citizen of the United States, residing at runna, in the county of Shiawassee, State of Michigan, have invented certain new and useful Improvements in Oement Brick Molds; and I do declare the following to be a full; clear, and exact description of the invention, such-as will enable others skilled in the art to which it appertains to make and use the same, reference being had totheaccompanying drawings, and to thefigures of reference marked thereon, which form a part of this specification.

This invention relates toa mold for cement bricks and artificial stones; and it consists in the construction and arrangement of parts hereinafterfully set forth, and pointed out particularly in the claims. a d

The object of the invention is to provide a simple and efficient mold in which cement bricks may be perfectly formed and from which they may be discharged in a perfect state. The above object is attained by the structure illustrated in the accompanying drawings, in which-e v Figure 1 is a perspective view of a mold embodying my invention. Fig. 2 is a vertical transverse section as on line 2 2 of Fig. 1.

Referring to the characters of reference, '1 designates a metal shell, formed, preferably, of steel, which constitutes the mold in which the brick is shaped. Secured tothe ends of said shell is a wide bail 2, having upon the inner faces of the vertical sides thereof the an gle-brackets 3. Passing vertically through the apertures 4: in said brackets are the legs of the supplementary bail 5, which lies within the bail 2. Mounted upon the lower ends of the vertical sides 6-of the supplementary bail 5 are the coiled springs 7, which are confined between the pins 8 in the legs of said bail 5 and the under face of the brackets 3.

Adapted to fit within the shell or mold l is a weighted follower 9, made, preferably, of iron and having a removable face-plate 10, which may be configured to give any desired design to the face of the brick. Attached to the plunger or follower 9 is a looped handle 11, having the vertical legs 12, which pass freely through the top of the bail 2. By means of this looped handle the plunger or follower may be moved vertically within the shell for the purpose of working and compressing the sand and cement and for discharging the brick from the mold after being formed.

Projecting from the legs 12 of the looped :handle are the pins 13, over which the supplementary bail 5 is adapted to be engaged, as shown in Fig. 1, when the follower is raised to exert an additional force thereon that assists in discharging the formed brick from the mold.

In the operation of this device in forming cement bricks the cement and sand are first mixed in the'form of mortar in a suitable mortar-box and the surface thereof leveled 0E by a straight-edge. The mold, with the follower drawn up, is then forced downward through the cement to the bottom of the box, which forms a bottom for the mold. The cement and sand within the mold are then compacted by a few vertical movements of the follower through the handle 11. The shell or mold is then withdrawn from the mortar, carrying the formed brick therein,and placed upon a suitable drying-board. The bail 5 is then drawn upwardly, so as to engage its top part over the pins 13 to compress the springs 7, when by a downward pressure upon the handle and an upward pull upon the bail 2 the brick will be forced from the mold onto the drying-board in perfect shape.

Having thus fully set forth my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. In a mold for cement bricks or artificial stones, the combination of a shaping-shell having a vertical bail attached thereto, a follower within said shell adapted to move vertically, a handle attached to said follower and extending vertically, through the medium of which the follower may be actuated independently of the shell, and means for exerting an upward pressure upon the bail and a downward pressure upon the handle when the follower is raised.

2. In a cement-brick mold, the combination of a shaping-shell having a verticallystanding bail attached thereto, a supplemen tary bail within the first-mentioned bail carrying compressible springs, a follower within said shell, a handle attached to said follower and passing vertically through said first-men- 15 tension upon said springs.

4. In a mold for cement bricks, the combination of a shaping-shell, a bail extending vertically from said shell, havinga transverse cr0ss-piece, a follower adapted to move vertically in said shell, having a looped handle extending therefrom, the vertical portions of said handle passing through and being guided in the transverse portion of said bail.

In testimony whereof I sign this specification in the presence of two witnesses.
